Above 55 °C the thermal curve pulls back; at 70 °C you lose about 15 % of the rating, so factor that into your enclosure layout if the panel runs hot. This unit delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 3.4 kA at 690 V. At 690 V the capacity drops to 3.4 kA, which still covers most motor branch circuits at that voltage. The ETU320 is an electronic overcurrent release with no voltage trigger, no undervoltage release, and no ground-fault monitoring built in. No communication function onboard — this is a plain line-protection breaker, not a metering or trip-data device. ## Lifecycle and sourcing — current production, no LTB watch needed The supplied basic switch variant is 3VA2063-5HL32-0AA0 — that is the base breaker without the auxiliary switches. The -0AC0 suffix adds the two HQ aux contacts. If you already have the -0AA0 in the panel and need the aux contacts, you can swap the switch block rather than replace the whole breaker, but the order code here is the complete assembled unit. That width is a standard 105 mm for a 3-pole SENTRON 3VA2 frame — it fits the same mounting footprint as other 3VA2 breakers in the 63 A range. The IP40 front protection means the operator-facing side is sealed against tools and wires over 1 mm, but the rear terminals are not sealed; mount it inside a panel with at least IP54 overall if the enclosure sees washdown. Power loss is 5.4 W maximum at rated load — negligible for most enclosures, but worth noting if you are packing a dozen breakers in a sealed box with no forced ventilation. ## Peer comparison — 3VA1010-2ED32-0JA0 The 3VA1010-2ED32-0JA0 is a smaller-frame SENTRON breaker (100 A frame, typically 16–100 A rating) with a different release — the 2ED32 designation points to a thermal-magnetic release, not the ETU320 electronic unit here. The 3VA2063-5HL32-0AC0 sits in the 3VA2 frame (160 A frame, 63 A plug) and gives you electronic trip adjustment. If your panel was wired for the 3VA1010, the mounting hole pattern and bus-bar centers are different — you cannot drop this 105 mm wide breaker into a cutout sized for the 3VA1 frame without re-drilling the mounting plate.","metaTitle":"Siemens 3VA2063-5HL32-0AC0 SENTRON MCCB, 63 A, 3-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2063-5HL32-0AC0 molded case circuit breaker, 63 A rated continuous current, 3-pole, ETU320 release, 187 kA at 240 V.
